Emerald Hill is a neighbourhood and a conservation area located in the planning areas of Newton and Orchard in Singapore. Former home to many members of the city-state's wealthy Peranakan community, it is located near Orchard Road. Many of its homes feature Chinese Baroque architecture. Emerald Hill is also the setting for some of the short stories by the late Singaporean author Goh Sin Tub. Many of the homes were designed by Mr R T Rajoo (Rethinam Thamby Rajoo Pillay) a prominent architect of those days who died in 1928 at his home in Tank Road, Singapore.

Cuppage himself moved from his residence in Hill Street to Emerald Hill in the early 1850s and lived in the area till his death in 1872. Here he built two houses (Erin Lodge and Fern Cottage) where he lived. After his death, Cuppage's plantation was left to his daughters and in 1890 it was sold to one of his sons-in-law, the lawyerEdwin Koek.

By the turn of the twentieth century, the 13.2 hectare land and its three houses (Erin, Fern and Claregrove) were the property of Seah Boon Kang and Seah Boon Kiat. In 1901, they subdivided the property into 38 plots and these were further subdivided, forming the land area of the terrace houses in Emerald Hill Road.

All three houses were subsequently demolished: Fern Cottage in 1906 made way for terrace houses; in 1924 Claregrove gave way to the Singapore Chinese Girls' School; Erin Lodge was replaced with more terrace houses.

Hullet Road was built in 1914 and named after R.W. Hullet, principal of Raffles Institution from 1871 and later Director of Public Instruction on his departure from Singapore in 1906 after having stayed here for 35 years. His name is also commemorated in Raffles Institution in the form of a Hullet Scholarship awarded since 1908. The road was named after Hullet at the request of Dr Lim Boon Keng, who was Hullet's pupil.
